Penned by Joss Whedon and set on Earth after Alien Resurrection, Alien 5 is one of the biggest sequels never to see the light of day. The Alien franchise is a success by any barometer or metric, spawning 4 mainline installments and 2 prequel films, with the original Alien‘s induction into the National Film Registry for historical preservation highlighting its cultural significance. All Alien installments center around the origins or activity of the iconic early Xenomorph, designed by legendary Swiss surrealist H.R. Geiger.
The final film in the original series, Alien Resurrection, ended with Call (Winona Ryder) and Ripley (Sigourney Weaver) floating towards a futuristic Earth after escaping the human/Alien hybrid.
